Abstract

This study was analyzes the effectiveness of worm droppings on the growth rate of catfish and kale in buckets. The dose of worm excrement given was 75, 125, and 175 grams in 40 liters water. The positive control used 5 ml of EM 4 and the negative control was given plain water. The growth of catfish was observed for 9 weeks and every two weeks the morphometric in catfish weight and length were observed. In the first 4 weeks, the weight of kale was measured and analyzed for SGR value (growth rate), Survival Rate, Food Convention Ratio, and catfish weight data. In stage 1, the growth rate (SGR) of treatment with vermicompost was 125 g (0.18%), vermicompost 75 g (0.18%), vermicompost 175 g (0.17%), EM4 (0.16%), and the last is plain water (0.13%). Survival rate at this stage is above 90%. In stage 2, the SGR was treatment with 175 g vermicompost, 125 g vermicompost, and 75 g vermicompost at 1.10%, followed by 1.06% plain water, and 1.05% EM4. The lowest survival rate in positive control. The result showed that the treatment with vermicompost was effective at the larval-juvenile stage (stage 1) of catfish with effective treatment at 75 grams.
